What I should have typed was:
# dnf update g* i* kd* kf* q* per* pyt* u* v* x* y* z*

An alternative to what I've been doing. When I can remember, I first change
to an empty directory before typing dnf, so bash has nothing local to find.

It would be nicer still to have the same option not to fill the filesystem
before installing as other distros, thus avoiding need for workarounds.
Second best would be Chris Murphy's suggestion: "dnf ... do a better estimate
... of free space before starting an upgrade in the first place", except that
it seems to conflict, based on my understanding of it, with the ostree
approach under construction.
